HENRY M. HOWLE'IT AND ALBERT LAESSELE, 0F SANDUSKY, OHIO.

MACHINE FOR MAKING TOE-GALKS.

To all whom it may concern:

Be it known that we, HENRY M. HOWLETT and ALBERT LAESSELE, citizens ofthe United States, residing at Sandusky, in the county of Erie, State ofOhio, have invented a new and useful Machine for Making Toe-Calks, ofwhich the following is a specification.

This invention relates to an improvement in machines for forminghorse-shoe calks.

The primary object of the invention is to provide a machine of thischaracter which will effectually form the calk and sever the same fromthe stock from which it is formed.

A further object of the invention is to provide means for forming thecalk and severing the same from the stock said means to be actuated by asingle movement of an operating lever.

With the foregoing and other objects in view which will appear as thedescription proceeds, the invention resides in the combination andarrangement of parts and in the details of construction hereinafterdescribed and claimed, it being understood that changes in the preciseembodiment of invention herein disclosed can be made within the scope ofwhat is claimed without departing from the spirit of the invention.

In the drawings,Figure 1 is a side elevation of the device one of theplates being removed to show the calk-forming mechanism. Fig. 2 is aside elevation, the other plate being removed to show the shearingmechanism. Fig. 3 is a detail view of the gage by means of which thelength of calk may be regulated. Fig. 4 is a side elevation of thecomplete machine; and Fig. 5 is a section taken on the line 55 of Fig.4.

In the drawings 10, 11, and 12 designate spaced supporting plates whichmay be supported by legs 13, 14 and 15, the leg 13 being secured betweenthe plate 10 and the plate 11, adjacent the ends of said plates and theleg 14 being secured between the plate 11 and the plate 12, the leg 15being secured between the plates 11 and 12, the offset end portions ofthe legs which are secured between the plates spacing said plates, theplates 10 and 11 adjacent the leg 15 being spaced by a suitable nut 16,said nut being held in place by the bolt 17, which extends through theextension 15 formed integral with the leg 15, the upper ends of saidplates being spaced by the nuts 16. The plates are provided withregistering apertures 18. Pivotally supported immediately Specificationof Letters Patent.

below the aperture formed in the plate 12 is a lever 19 which isprovided with a shearing knife 20. A second lever 21 is pivoted adjacentthe top of said plate, the lever 21 being connected to the lever 19 bymeans of a link 22, the end portions of the link 22 and the lever 19being connected, said link being connected centrally to the lever 21. Anoperating lever 23 is provided with the offset extension 24, which ispivo-tally supported adjacent the upper corner of the plate, thisoperating lever 23 being connected to the end portion of the lever 21 bymeans of a link 25. Thus, it will be seen that as the operating lever 23is forced downward, the link 25 will assume the position shown in Fig.4, the lever 21 swinging the lever 19 on its pivot, the knife 20shearing the material which maybe placed between the walls of theregistering apertures 18 of the plates.

Secured to the plate 11 is a stationary knife 26 which co-acts with theknife 20, the stationary knife being held against lateral displacementby means of the U-shaped member 27 which is bolted to the plate 11 andwhose extended portions 28 contact with the knife 26. The calk formingmechanism is positioned on the other face of the plate 11. A lever 29 ispivotally supported between the plates 11 and 12 at a point adjacent theedge 30 of the plates, said lever be ing formed with a reduced extension31 and at a point adjacent said extension with an enlargement 32, said.enlargement receiving one of the members 33 of the calk-formingmechanism. A jaw 34 is supported directly opposite of the lower portionof the lever 29 and said jaw 34, and the lower portion of said leverforms a pair of jaws which are adapted for movement toward and away fromeach other, the jaw 34 being provided with a calk-forming member 35which is similar to the member 33 carried by the lever 29. A guide 36for said members 35 and 33 is positioned between the jaws, said guideconsisting of a plate spaced from the plate 11 and extending asufficient distance between the jaws to overlap the lower portions ofthe members 35 and 33 when the jaws are in their open position as shownin Fig. 1. The end portions of the jaws have a toggle connection whichconsists of the rotatably supported member 37, the end portions of whichare connected by means of links 38 and 39 to the end portions of thejaws 34 and 29, respectively. Thus it will be seen that as the lever 29is swung on its pivot, its enlargement 32 traveling toward the aperture18, will impart a simultaneous movement to the aw 34, the enlargedportion of which will travel toward said aperture. Thus the materialwhich has been previously placed within the slot or aperture 18 will begrasped between the formers 33 and 35, these formers pressing thematerial into proper shape to form the article. Attention is called tothe fact that these formers may be conveniently removed and replaced inorder to vary the shape of the calk, the guide 36 preventing lateralmovement of the formers as the jaws are brought together. The jaw 29 isconnected to the lever 21 by means of a link 38, the end portions ofsaid lever and link being pivotally connected, said link being pivotallyconnected to the lever 21 at a point below its center, the link havingits end portion 39 off-set in order that its body portion may lie inalinement with the lever 21 and at the same time impart a propermovement to the lever 29. Thus it will be seen that as the operatinglever 23 is depressed as shown in Fig. 4, the links 22 and 38 will besubstantially parallel, the shearing mechanism and forming mechanismbeing consonantly actuated by the movement of said lever.

Attention is called to the fact that the formers will travel in advanceof the shearing mechanism thus forming the calk before the same issevered, the formers normally lying in contact with the metal from whichthe calk is formed.

In order to regulate the lehgth of the calk which is formed, an L-shapedbracket 40 is supported by the plate 10, the extension 41 of said platebeing provided with a slot 42, said extension 41 supporting anadjustable gage 43 which is slot-ted at 44 to receive the extension, thegage 43 being formed with an extension 45 which lies parallel with theextension 41, a screw 46 being carried by the extension 45, the endportion of said screwbeing provided with a nut which contacts with theextension 41 permitting the adjustment of the gage guide 43. This guidemay bev adjusted in order to regulate the length of the calk to be cut,the bar of material from which the calk is formed be ing placed with itsend portion in contact with the face of the gage guide 43.

The many advantages of a machine of this character will be clearlyapparent and it will be noted that a single operation of the machineeffectually forms the calk and severs the calk from the material fromwhich the same is formed, the two mechanisms being actuated consonantly,the forming mechanism performing its function slightly in advance of theshearing mechanism. t

Particular attention is called to the PGCUl-a iar arrangement andpositioning of the formers, the jaws which support the same beingsimultaneously actuated.

Attention is called to the fact that the machine is of such aconstruction as may be easily and economically manufactured the variousparts being readily assembled.

What is claimed is 1. In a calk-forming machine, a pivotally supportedshearing member, a pivotally sup ported former, a pivoted lever, saidforming and said shearing members having link con nections with saidlever, an operating lever, and a link connection between said operatinglever and said first mentioned lever.

2. In a calk-forming machine, a plurality of formers, means forsimultaneously moving said formers to contact with the stock of whichthe calk is formed, and a shearing member having an operative connectionwith and operating consonant with the formers, said member being activeto the stock while the same is held by said formers, said shearingmembers and formers being active in the same horizontal plane.

8. In a calk-forming machine, a plurality of pivotally supportedformers, said formers being movable simultaneously, a shearingmechanism, an operative connection be-' tween said shearing mechanismand thei formers, said formers supporting the stock while the shearingmechanism is active.

4. In a calk-forming machine, a plurality of movable formers, saidformers being movable simultaneously, a shearing mechanism, an operativeconnection between said shearing mechanism and the formers, said formerssupporting the stock while the shearing mechanism is active.

In testimony that we claim the foregoing as our own, we have heretoaflixed our signatures in the presence of two witnesses.
